Autonomous Agent Nanopayment Protocol (ArcNano)

Live multi-agent payment settlement deployed on Circle's Arc Layer 1. Autonomous AI agents pay for inference per-token with zero surveillance, sub-8ms client verification, and sponsored L1 settlement.

Live Nanopayment Execution Pipeline

Executes a real on-chain transaction on Arc Testnet between Agent A and Agent B with mathematical ZK note settlement.

0/5 Daily Runs
1
Agent A: Cryptographic Note SynthesisIn-Memory

Agent A synthesizes a shielded note commitment Poseidon(0.01 USDC, secret, nullifier_seed) entirely in local memory.

2
Arc L1 Shielded Deposit BroadcastOn-Chain Arc L1

Agent A deposits 0.01 USDC note commitment into ArcNanoPool. Leaf inserted into on-chain 20-level Merkle tree.

Ready for broadcast
3
Off-Chain AI Inference HandshakeP2P HTTP 402

Agent A queries Agent B: HTTP POST /v1/chat/completions (512 prompt tokens). Sends SpendProof in X402 payment header.

4
Sub-8ms ZK Verification & ASP Compliance CheckHalo2 WASM

Agent B validates Groth16 pairing check & verifies deposit non-membership in OFAC sanctioned sets via Association Set Provider root.

5
Zero-Latency LLM Token StreamingInstant Stream

Agent B verifies payment validity off-chain in 7.2ms. HTTP 200 OK: Streams 4,096 tokens to Agent A with ZERO block delay.

6
On-Chain Spend Settlement on Arc TestnetArcscan Settlement

Agent B broadcasts spend(proof, agentB) on ArcNanoPool. 0.01 USDC paid out directly. Nullifier permanently marked as spent.

Ready for broadcast
7
Replay Attack Defense VerificationRevert Defended

Attempted replay of same spend proof reverts on-chain with NullifierAlreadySpent. Solvency and privacy mathematically guaranteed.
